Pomorie (Bulgarian: ) is a town and seaside resort in southeastern Bulgaria, located on a narrow rocky peninsula in Burgas Bay on the southern Bulgarian Black Sea Coast. It is situated in Burgas Province, 20 km away from the city of Burgas and 18 km from the Sunny Beach resort. The ultrasaline lagoon Lake Pomorie, the northernmost of the Burgas Lakes, lies in the immediate proximity. The town is the administrative centre of the homonymous Pomorie Municipality. Pomorie is an ancient city and today an important tourist destination. As of December 2009, it has a population of 13,569 inhabitants. It lies at 42°33N 27°39E / 42.55°N 27.65°E / 42.55; 27.65. Pomorie was founded by the Ancient Greeks under the name Anchialos (Greek: ), deriving from Ancient Greek "anchi-" ("near, close to") and "als-" (either "salt" or a poetic and uncommon word for "sea"). In Latin, this was rendered as Anchialus. The Bulgars called the town Tuthom, though it's more common name in Bulgarian was , Anhialo based on the Greek name. During the Ottoman rule, the town was called Ahyolu. In 1934 the town was renamed to Pomorie, from the Bulgarian "po-" (in this context "by, next to") and "more" ("sea"), corresponding to one of the two etymologies of the original Greek name. Possibly founded in the 5th or 4th century BC as a colony of Apollonia (today Sozopol), Anchialos was mentioned in Strabo's Geographica as a small town. It was briefly captured by Messembria (Nesebar) in the 2nd century BC, but reconquered by Apollonia and its fortified walls destroyed.
